Magnetic resonance imaging (MRI) is one of technology’s most advance diagnostic tools for today’s physician. It allows your physician to see inside your body without surgery or the use of ionizing radiation. MRI uses a powerful magnet, low-intensity radio waves and computer technology to create detailed images of the soft tissues, muscles, nerves and bones in your body.
How MRI Scanners Work
The main component of the scanner is a magnet that allows your body to receive radio signals from the magnetic resonance system. Your body reacts by sending its own radio signals back to the machine. The radio frequency is then computer-processed and turned into detailed images.
Preparing for Your Test
In general, there are no special preparations to follow before your exam. Because MRI uses a strong magnetic field, metal objects will interfere with the scan; for your convenience, we provide a locker to store your barrettes, jewelry and credit cards. We ask that you wear comfortable, loose-fitting clothing, but you may be asked to change into a hospital gown. Please check the following list carefully. You can not be examined by MRI if you have the following:
- A pacemaker
- Aneurysm clips in the brain
- Inner ear implants
- Metal fragments in one or both eyes
- Implanted spinal cord stimulator
- If you are pregnant, think you might be or
are breast feeding
- If you have anemia or any diseases that
affect red blood cells
- If you have asthma or other allergic
Please consult your physician if you have any questions about your eligibility.
Understanding Contrast Media
Certain types of MRI scans require the use of a paramagnetic agent or contrast media. This contrast media, which is given intravenously before the exam, highlights certain body parts. When needed, it will be discussed in detail with eligible patients. Tell your physician before your exam if you have ever had an adverse reaction to contrast media.
